9058fc44e6 Allow to validate the config file without X.
We're going to call parse_configuration() very early if -C is given on
the command line. Instead of the previous "only_check_config", which has
been a global variable, we now simply pass use_nagbar as false if we're
just validating.

This causes the whole parsing to run without X and of course without
starting nagbar and displaying the errors to standard out/error instead.

The return code of parse_configuration() is now a boolean which
represents whether an error occured during parsing and the programs exit
code is returned accordingly.

Although the config parser still has a lot of side-effects, we now can
parse without the need to have an XCB connection. A nicer implementation
would be to just set the new font and load it just after we're done
parsing, but to ensure we don't break functionality we just load a dummy
FONT_TYPE_NONE if XCB isn't available. The main reason for going this
route is that it's a bit difficult to test fonts in a distribution
agnostic way without bundling fonts with i3 (or Xdummy to be more
exact).

9200094203 format **/*.c with clang-format-3.5
This has multiple effects:

1) The i3 codebase is now consistently formatted. clang-format uncovered
   plenty of places where inconsistent code made it into our code base.

2) When writing code, you don’t need to think or worry about our coding
   style. Write it in yours, then run clang-format-3.5

3) When submitting patches, we don’t need to argue about coding style.

The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.

0883dfbe14 only LOG() the DPI when it changes, DLOG() it otherwise (Thanks lkraav)
This avoids flooding stdout every time some text (e.g. a window
decoration) is drawn, yet leaves the message in place when it’s actually
relevant (upon DPI changes).

1d6450f0e8 libi3/font: Set DPI for the pango context
The pango font specification accepts a font size in points, but pango
defaults to a DPI of 96. Create a default PangoContext (which
internally creates a default PangoCairoFontMap as usual) and set the
DPI to the value of the root Screen manually.

Fixes #1115

a49dfaf26c libi3/font: Draw the text at the expected place
When drawing a text with Pango, shift it to the top according to the top
if the glyph if taller than expected
We always shift of (height - savedHeight) which is a no-op for normal glyphs

2896ae8057 logging: make libi3 use verboselog()/errorlog(), provide it in each caller
While this is a bit ugly, it makes the log messages end up where they
are supposed to: in the shmlog/stdout in case of i3 and on stdout in
case of utilities such as i3-input

206b96202c Use (void) instead of () for functions without args (Thanks fernandotcl)
See also:
http://article.gmane.org/gmane.linux.kernel/1268792

The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.

340592a532 Invalidate cached pixmaps on reload and redraw.
After a reload, the drawing parameters for the decorations might
have changed, so we need to invalidate the cache and force a redraw
of the currently visible decorations. Also, don't leak the previous
font when reloading by freeing it before parsing the config.

5c2088c87e Enhance libi3 and use it in i3bar.
Abstracted draw_text and predict_text_width into libi3. Use
predict_text_width from libi3 in i3 too. This required tracking
xcb_connection in a xcb_connection_t *conn variable that libi3
expects to be available in i3bar.
